Use the coordinates of the two black dots:
(2,3) and (7,6)
Slope is the change in Y over the change in X:
Slope = (6-3) / (7-2)
Slope = 3/5
Tangent always meets radius at 90° angle.
Angle ABC = 90° so Pythagoras' theorem applies.
r² + 4² = (r+2)²
r² + 16 = r² + 4r + 4
12 = 4r
r = 3
Answer:
Step-by-step explanation:
Earnings = 5 + 7.50x You want to earn 50.00
50 = 5 + 7.50x Set up equation
45 = 7.50x Subtract 5
45/7.50 = (7.50/7.50) x Divide by 7.5
x = 6
You need to work 6 hours.
Both methods start out with a factor<span> tree. A </span>factor<span> tree is a diagram that is used to break down a number into its </span>factors until<span> all the numbers left are </span>prime. The first way you can use a factor<span> tree to find the </span>factorization of a number is to divide out prime<span> numbers only. Let's </span>factor<span> 24 using this method.</span>
Answer:
the answer is the letter a) -sin x
Step-by-step explanation:
Simplify the expression.
sine of x to the second power minus one divided by cosine of negative x
(1−sin2(x))/(sin(x)−csc(x))
sin2x+cos2x=11−sin2x=cos2x
cos2(x)/(sin(x)−csc(x))csc(x)=1/sin(x)cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))sin2(x)− 1=-cos2(x)cos2(x)/(( -cos2(x))/sin(x))
=-sin(x)
